1022

If a network device has a mask of /28, how many IP addresses are available for hosts on this network?

14

What is the prefix for the host address 2001:DB8:BC15:A:12AB::1/64?

2001:DB8:BC15:A

Which subnet mask would be used if 5 host bits are available?

255.255.255.224

How many usable host addresses will the subnet 255.255.255.248 provide?

6

Which two reasons generally make DHCP the preferred method of assigning IP addresses to hosts on large networks? (Choose two.)

It eliminates most address configuration errors It reduces the burden on network support staff

What two statements describe characteristics of Layer 3 broadcasts? (Choose two.)

Routers create broadcast domains. A limited broadcast packet has a destination IP address of 255.255.255.255

What is a result of connecting two or more switches together?

The size of the broadcast domain is increased.

What are two reasons a network administrator might want to create subnets? (Choose two.)

improves network performance easier to implement security policies

hat are two types of IPv6 unicast addresses? (Choose two.)

loopback link-local

A network administrator needs to monitor network traffic to and from servers in a data center. Which features of an IP addressing scheme should be applied to these devices?

predictable static IP addresses for easier identification*

How many bits must be borrowed from the host portion of an address to accommodate a router with five connected networks?

three

Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures?

tunneling
